Yes, GRAPHS. Why limit to trees now that hypertext is freeing us from
hierarchical structures :-)
I would do it somehing like this
<graphlist xmin=0 xmax=1000, ymin=0, ymax=1000>
<item x=100,y=200> bar </item>
<item x=700,y=300> foo </item>
Now a clever client would convert the coordinates to
whatever coordinates it internally uses to plot the
items and the link, a less clever one would just display
the items as a list (maybe with leading spaces added)
There was some talk about this a long time ago. Then
the question of who (server, client, author) should
construct these graphs was brought up.
I think it is the authors job. Of course it would be nice if they
could be constructed by the server or the client on the fly, but I
think it is asking too much.
Some network-analysis programs can be used to perform
multidimensional scaling, clustering etc. to help the
author in map-making, but I think it is mainly handcraft
(and quite demanding craft also, I fear).
